Opposition says forensic expert defects from Syria

A Syrian forensic medicine expert with evidence of President Bashar Assad's involvement in a chemical weapons attack near Aleppo in March has defected to Turkey, the Istanbul-based opposition said on Tuesday.

Abdel-Tawwab Shahrour, head of the forensic medicine committee in Aleppo, would make public his evidence of the Assad administration's involvement in a March 19 chemical attack in Khan al-Assal, a Syrian opposition coalition spokesperson said. (Reuters)
